O impacto do terrorismo no mercado de capitais

Abstract

Este trabalho tem como propósito analisar o impacto do terrorismo nos mercados de capitais dos países e na indústria dos transportes e, ainda, aferir acerca da resiliência dos mesmos com o decorrer do tempo. Para tal, são estudados oito ataques terroristas recentes ocorridos na União Europeia e comparados com dois ataques semelhantes mais antigos ocorridos na mesma região. Os índices bolsistas utilizados neste estudo dizem respeito ao principal índice do país onde ocorreu o ataque e aos índices FTSE Euro 100, S&P 500 e Dow Jones Singapura, representativos do mercado europeu, americano e asiático, respetivamente. A metodologia de estudo de eventos, que se baseia na identificação de retornos anormais para avaliar o impacto de um acontecimento num determinado índice ou ação, foi a utilizada para a realização deste trabalho. Os resultados deste trabalho mostram que não foi possível determinar de forma concreta o padrão de um ataque terrorista nos mercados de capitais. Contudo, os resultados apontam para uma maior capacidade de recuperação, com o decorrer do tempo, por parte dos mercados face a ataques terroristas.

ABSTRACT: The present work aims to analyze the impact of terrorism on capital markets of the countries and in the transport industry, and to assess their resilience over time. To this end, eight recent terrorist attacks in the European Union have been studied and compared to two older similar attacks that happened in the same region. The stock indices used in this study relate to the main index of the country where the attack occurred and the FTSE Euro 100, S&P 500 and Dow Jones Singapore indices, representing the European, American and Asian markets, respectively. The event study methodology, which is based on the identification of abnormal returns to evaluate the impact of an event on a given index or action, was the one used to execute this work. The results of this work show that it was not possible to determine concretely the pattern of a terrorist attack on the capital markets. However, the results point to a greater capacity for market recover over time on terrorism.
